This gemstone, a variety of the mineral corundum, has been cherished for centuries for its captivating hues and resilience. As one of the hardest gemstones available, second only to diamond, it is an ideal choice for jewelry meant to be worn and enjoyed daily. This article explores the history, geological origins, gemological properties, and cultural significance of pink sapphire, drawing on authoritative sources to provide a comprehensive guide for gemstone enthusiasts, collectors, and anyone interested in this remarkable October birthstone.
History and Lore
The pink sapphire, a variety of corundum, possesses a long and storied history that extends back to ancient civilizations. While the blue sapphire is more commonly associated with the traditional September birthstone, the pink variety has been linked to October for much of the 20th century. Its vibrant hue, ranging from soft blush to deep rose, has captivated jewelers and collectors for centuries.
Ancient cultures held sapphires in high esteem. In Persian mythology, it was believed that the Earth rested on a colossal sapphire, and that the sky's blue color was a reflection of this immense gemstone. This belief underscores the gemstone's perceived power and divine connection. Over time, the sapphire’s use in jewelry and ceremonial objects expanded, and its various colors, including pink, began to be appreciated for their unique beauty and symbolic meanings.
In the 20th century, the pink sapphire found its official place as a birthstone for October. This designation was influenced by the gemstone's growing availability and its aesthetic appeal. Jewelers and gemologists recognized the pink sapphire not only for its visual charm but also for its practicality, being one of the hardest gemstones available, second only to diamond on the Mohs scale. Historically, sapphires have been treasured by royalty and clergy alike for their beauty and supposed protective powers. Pink sapphire, in particular, has been valued for its aesthetic appeal and symbolism, often associated with love and compassion.
Geological Formation and Global Sources
The pink sapphire is a type of corundum, a mineral composed of aluminum oxide (Al₂O₃). Its distinctive pink coloration is due to trace amounts of chromium or manganese within its crystal structure. Corundum forms under high-pressure and high-temperature conditions deep within the Earth’s crust, typically in metamorphic or igneous rock formations.
Pink sapphires are mined in various locations around the world. Sources of this gemstone include Australia, Sri Lanka, and the United States. The availability of pink sapphire in these regions ensures that it remains accessible to a wide range of consumers, contributing to its popularity in fine jewelry.
Gemological Properties
Pink sapphire is renowned for its exceptional durability and captivating luster. Its most notable property is its hardness, which rates 9 on the Mohs scale. This makes pink sapphire one of the hardest gemstones, second only to diamond. This exceptional durability makes it an excellent choice for everyday wear, capable of withstanding the rigors of daily life without losing its luster. This characteristic is particularly important for jewelry items like rings and bracelets, which are subject to frequent contact and potential abrasion.
The color of pink sapphire can vary significantly, from delicate pastels to vivid magenta hues. This range of shades allows for a wide array of jewelry designs, appealing to diverse tastes. The gemstone's chemical composition, aluminum oxide (Al₂O₃), is the same as that of ruby and blue sapphire, with the trace elements (chromium or manganese) determining its pink coloration.

Care and Cleaning
Given its exceptional hardness, pink sapphire is a relatively durable gemstone that can withstand daily wear. However, proper care is essential to maintain its brilliance and longevity. While it is resistant to scratching from most materials, it can still be damaged by sharp blows or extreme temperatures.
For cleaning, pink sapphire can be safely washed with warm, soapy water and a soft brush. It is important to avoid harsh chemicals and ultrasonic cleaners, which could potentially damage the stone or its setting. As with all fine jewelry, it is advisable to have pink sapphire pieces inspected periodically by a professional jeweler. A jeweler can check for any signs of wear, damage, or loose settings and provide recommendations for care and maintenance. This is particularly important for rings and other jewelry that are worn frequently and are more likely to experience wear and tear.
When storing pink sapphire jewelry, it should be kept separately from other gems to prevent scratching. Although pink sapphire is very hard, other stones like diamond could potentially cause damage if they come into contact.
